Examination
1. The ELD system detects signs of overload in the electrical circuits of external lighting and signaling systems, fuel injection, charging, etc. The first symptom of this kind of overload is a violation of the stability of the power supply at idle engine speed. Failure of the detector leads to the recording of a fault code P1297 or P1298 in the self-diagnosis system memory.
2. Remove ELD (see paragraph 1 below) and disconnect the wiring from it. Measure the voltage between terminal 1 (+) and ground on the connector on the side of the harness with the ignition on (do not start the engine). The nominal value is equal to the battery voltage. If there is no voltage, check the condition of the wiring between the No. 6 15A fuse and the detector.
3. With the ignition on (do not start the engine) measure the voltage between terminal 3 (+) and ground on the connector on the harness side. The required value is 4.5÷5.0 V. If there is no desired result, check the condition of the ELD wiring in the area between the engine and the generator.
4. Make sure there is continuity between terminal No. 2 and ground.
5. If the above checks fail, replace the ELD.
Replacement
1. The ELD box fits inside the fuse/relay box in the vehicle's engine compartment. Disconnect the negative cable from the battery.
Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to activate the audio system!
2. Remove the two mounting screws, remove the ELD block from the central part of the mounting block and disconnect the electrical wiring from it.
3. Installation is carried out in the reverse order.
